The FBI's Mexico City file on the Oswald visit to Mexico City and the various conspiracy allegations surrounding that visit. This recent version of the file has far fewer redactions and withholdings than the 1980 version, but is only a partial version.

This file consists of JFK assassination case file documents held at FBI headquarters in Washington DC. These reference materials presumably allowed for quick inspection by FBI supervisors during the HSCA investigation, without having to call out to Central Records or field offices.

This voluminous collection, declassified in the late 1990s, consists of FBI files on various persons and organizations, supplied to the House Select Committee on Assassinations during its investigation.
